AVStream Driver Reference Information

Each Video Filter has one Capture Pin and one Preview Pin. A pin is the source or destination of a video or audio stream. A video capture pin is a general purpose pin used for capture to a file, an encoder, an on-screen renderer, or any other destination. A video preview pin is mainly intended for on-screen rendering. Each Osprey Video Filter also has a Closed Caption pin and a Vertical Blanking Interval (VBI) pin for capture of specialized ancillary data.

On top of each Osprey logical Audio Device, one Audio Filter is created, with one or more pins capable of sourcing one or more audio streams. There is not much practical distinction between an Audio Device and an Audio Filter in either the SimulStream or non-SimulStream cases.

Both devices, filters, and pins may have associated Properties. Properties are control parameters that can be read from or written to the component. Some Property Pages are standard Windows DirectShow pages. For example, the Property Page for an individual pin is a standard DirectShow page. The Video Proc Amp and Video Decoder Pages are also DirectShow-standard. The rest are proprietary to the Osprey driver.

As a user, you interact with Property through visual Property Sheets, Property Pages, or Property Tabs that are part of a tabbed dialog. As a programmer, you can set properties directly from within the code of your application, using either the standard DirectShow API or the custom Osprey extension API that is available from ViewCast in a software development kit (SDK).
